Buggerror Rosemary (or Ninten, as his name is later changed to) is a character in Mother who resides in the eastern part of Spookane. His family lived in the Rosemary's house prior to Ninten's arrival, the manor itself having since been overtaken by monsters. Buggerror and his parents can be found in the Spookane residential area, where the rest of the inhabitants are located, after Ninten has learned the fourth melody. Buggerror also gets renamed to whatever the player has chosen to name Ninten in the beginning of the game.

Trivia

Buggerror's sprite was likely chosen for its resemblance to Ninten's, sharing his blue shirt and red hat colors.
